.SH DESCRIPTION
|
|
The QChildEvent class contains event parameters for child object events.
|
|
.PP
|
|
Child events are sent to objects when children are inserted or removed.
|
|
.PP
|
|
A ChildRemoved event is sent immediately, but a ChildInserted event is \fIposted\fR (with QApplication::postEvent()).
|
|
.PP
|
|
Note that if a child is removed immediately after it is inserted, the ChildInserted event may be suppressed, but the ChildRemoved event will always be sent. In this case there will be a ChildRemoved event without a corresponding ChildInserted event.
|
|
.PP
|
|
The handler for these events is TQObject::childEvent().
|
|
.PP
|
|

|
|
